Great to see a win again, well done Petra! Every match now is really valuable so winning is paramount. Cornet (assuming she wins R1) will definately be a challenge and I won't hold my breath, but Petra should enter this as if she has nothing to lose (which is not far from truth actually). Hope she can get as many matches under her belt before RG (maybe even some on ITF's if necessary), cause in the light of defending close to 300 points she'll have to be really ready and extra motivated, not to mention confident.
Good luck in R2
